FLOORJOINT FOR WATER-CLOSETS.

Specification of Letters Patent.

Application filed. April 30, 1906- $erial No. 314,380

To all whom it may concern:

Be it known that I, JoHN W. CRAWFORD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Floor-Joints for Water-Closets; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to a novel construction in a floor-joint forwater-closets, the object being to provide means for coupling the watercloset with the soil pipe through the floor adjustably and by means of arelatively unbreakable joint, and consists in the features ofconstruction and combinations of parts hereinafter fully described andclaimed.

In the accompanying drawings illustrating my invention: Figure 1 is acentral vertical section of a coupling constructed in accordance with myinvention showing its connection with the horn of the closet and withthe soil pipe. Fig. 2 is a similar section showing a slightly modifiedconstruction.

' In coupling water-closets with the soil pipe, which latter isgenerally disposed in the wall behind the closet, an L-shaped pipe A isemployed, one end of which is suitably connected with the soil pipe andthe other end of which is disposed below an opening in the floor B atthe point where the water-closet is to be located. So far as I aminformed, this connection of said pipe A with the water-closet C hasgenerally been made by means of a short length of lead pipe secured atone end to said pipe A and at its other end to a metal ring supportedupon the floor and to which the horn or discharge end of thewater-closet is suitably secured.

The lead-pipe connection has been found to be undesirable by reason ofthe fact that it cannot withstand the strains to which it is subjectedby settling of the building, warping of floors and other causes andbreaks, thereby establishing a leak through which water finds its wayand ruins the ceiling of the floor beloW and is otherwise objectionableand unsanitary.

My present invention is designed to overcome these objections and at thesame time provide a floor connection which is more readily and easilyeffected, will readily withstand all strains without breaking and whichwill readily permit of readjustment if this should be at any timerendered necessary by any cause affecting such connections. To this endthe vertical arm D of the pipe A is preferably internally threaded andan externally threaded sleeve E mounted therein, the latter beingprovided at its upper end with a flaring mouth F and with an annularflange G, the latter being adapted to rest upon the floor and beingprovided in its lower face with an annular recess H'in which the headsof bolts I passing through openings in said flange and in the flange Jon the horn K of the closet, are adapted to be received. The deliveryend of said horn K is externally beveled, and the angle of the flaringmouth F of said sleeve differs from the angle of bevel of said deliveryend of said horn so that the annular space between the inner wall ofsaid flaring mouth and the outer beveled wall of the delivery end ofsaid horn will converge at its lower end. In the said annular space asuitable packing ring L is adapted to be compressed to effect afluidtight joint and by rendering the annular space receiving saidpacking-ring smaller at its lower than at its upper end, the saidpacking ring will obviously be prevented from dropping into thesoil-pipe and clogging or obstructing the latter. It will be noted thatsaid sleeve E may be screwed down until the flange thereof rests firmlyupon the floor and the closet thus also held firmly in position. If bysettling of the building shrinking of the floor, or other causes thesaid sleeve should be sprung upwardly off the floor, the closet mayreadily be disconnected and the said sleeve readjusted.

The sleeve is preferably disposed inwardly of the pipe A, but may, asshown in Fig. 2 be externally disposed on said pipe A by externallythreading the latter and internally threading the former. In eithercase, however, a suitable substance such as red-lead, white-lead,litharge or the like is smeared on the threads before connecting so thata fluid-tight joint is effected. It is also essential that said sleevebe made of brass or similar metal so that it will not become practicallyinseparable from said pipe A.

The disposition of the sleeve internally of the pipe A is far moreadvantageous than the external disposition of the same and, in fact, thelatter is so objectionable by reason of the annular shoulder presentedthereby upon which sewage may lodge, that its use is entirely precluded.By internally disposing said sleeve no means for lodgment of sewage isafforded and the construction is rendered far cheaper for the reasonthat the operation of internally threading the vertical arm D of thepipe A is considerably easier and cheaper than externally threading thesame and the saving in brass or similar metal effected by making thesleeve E of smaller diameter is very considerable.

I claim as my invention:

A device of the kind specified, comprising a soil pipe connection, asleeve having threaded connection therewith, and adapted to pass throughan opening in the floor,

an annular flange on the upper end of said sleeve integral I tween thesame, and packing disposed in said annular 10 therewith and providedwith openings and having an space annular recess in its lower face,bolts having their heads In testimony whereof I have signed my name inpresence disposed in said recess and passing through said openings oftwo subscribing Witnesses.

and through openings in a flange on the closet, to secure the latter,said sleeve having a flaring mouth and said closet having a tapereddischarge horn, the taper of the latter and said mouth of said sleevebeing differential to provide an annular space convergent at its lowerend be- JOHN W. CRAWFORD.
